Abstract

This study evaluated the influence of different translucent resins (Z350 and Opallis) for customizing fiber posts and light-curing the cementation system using different LED equipment (V, Valo or R, Radii-Cal) on the bond strength and adhesive failure pattern at 24 h and 6 months. Eighty roots were prepared and divided into 4 groups (n=20): ZV (Z350 resin and LED Valo), ZR (Z350 resin and LED Radii-Cal), OV (Opallis resin and LED Valo), OR (Opallis resin and LED Radii-Cal). After post space preparation, the fiber post was customized and cemented with self-adhesive cement and light-curing using V or R LED equipment. Bond strength values were submitted to 2-way ANOVA test. ZV and ZR showed higher bond strength values than the other groups at 6 months of evaluation (p<0.05). The Z350 resin has a favorable influence on the bond strength of self-adhesive cement to root dentin, regardless of the LED polymerization equipment used.

使用不同的半透明复合树脂定制纤维桩对自粘牙胶与根部牙本质粘接强度的影响。

本研究评估了用于定制纤维桩的不同半透明树脂（Z350 和 Opallis）以及使用不同 LED 设备（V，Valo 或 R，Radi-Cal）光固化粘接系统对 24 小时和 6 个月后粘接强度和粘接失败模式的影响。制备的 80 根牙根分为 4 组（n=20）：ZV（Z350 树脂和 LED Valo）、ZR（Z350 树脂和 LED Radi-Cal）、OV（Opallis 树脂和 LED Valo）、OR（Opallis 树脂和 LED Radi-Cal）。在牙槽骨预备后，定制纤维桩并使用自粘固剂粘接，然后使用 V 或 R LED 设备进行光固化。粘结强度值进行了双向方差分析。在 6 个月的评估中，ZV 和 ZR 组的粘接强度值高于其他组（p

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
